Brillouin Laser Based on High Q Fiber Ring Resonator
Stimulated Brillouin scattering is an effective way to achieve a laser with low background noise due to its narrowband gain. Based on a high Q fiber ring resonator, a Brillouin laser with low noise is studied. The pump light is locked into a single-mode ring resonator with a length of 8 m by the Pound-Drever-Hall (PDH) locking technique, and a backward Stokes light with a frequency difference of 10.81 GHz from the pump light is obtained. The frequency noise of the Stokes light is measured by the correlative delay self-heterodyne method. The experimental results show that the threshold of the Brillouin laser based on the fiber ring resonator is 5.3 mW. In the high-frequency part (the frequency
